Fix:
assertTrue ( ( "Label<seq2seq4repair_space>should<seq2seq4repair_space>not<seq2seq4repair_space>be<seq2seq4repair_space>null<seq2seq4repair_space>or<seq2seq4repair_space>empty<seq2seq4repair_space>for<seq2seq4repair_space>" + name ) , ( ( label != null ) && ( ( label . length ( ) ) > 0 ) ) ) ;
